On balanced sequences and their critical exponent

Theoretical Computer Science, 2023
We study aperiodic balanced sequences over finite alphabets. A sequence vv of this type is fully characterised by a Sturmian sequence u and two constant gap sequences y and y'. We show that the language of v is eventually dendric and we focus on return words to its factors. We develop a method for computing the critical exponent and asymptotic critical

On a p-Laplacian system with critical Hardy–Sobolev exponents and critical Sobolev exponents [PDF]

Ukrainian Mathematical Journal, 2012
In this paper, the existence results of positive solutions for the semiliner elliptic system \[ \begin{cases} -\text{div} (|\nabla u_i|^{p-2} \nabla u_i) - \mu \frac{|u_i|^{p-2}u_i}{|x|^p} \\ = \frac{1}{p^*} F_{u_i}(u_1,\ldots,u_k) + \frac{|u_i|^{p^*(t)-2}u_i}{|x|^t} + \lambda \frac{|u_i|^{p-2}u_i}{|x|^s}, \quad x \in \Omega, \\ u_i=0 \quad \text{on} \;

Measures of critical exponents in the four-dimensional site percolation [PDF]

, 1997
Using finite-size scaling methods we measure the thermal and magnetic exponents of the site percolation in four dimensions, obtaining a value for the anomalous dimension very different from the results found in the literature.

Crossover of critical behavior and magnetocaloric effect in FePd2Te2 with one-dimensional Fe chains [PDF]

APL Materials
Recently, a two-dimensional ferromagnet FePd2Te2 exhibiting easy-plane anisotropy with a quasi-one-dimensional spin system has been discovered. We report the magnetic critical behavior and magnetocaloric effect of FePd2Te2 single crystals with magnetic ...

Critical exponents at the unconventional disorder-driven transition in a Weyl semimetal [PDF]

, 2015
Disordered noninteracting systems in sufficiently high dimensions have been predicted to display a non-Anderson disorder-driven transition that manifests itself in the critical behavior of the density of states and other physical observables.

Quantum critical exponents for a disordered three-dimensional Weyl node [PDF]

, 2015
Three-dimensional Dirac and Weyl semimetals exhibit a disorder-induced quantum phase transition between a semimetallic phase at weak disorder and a diffusive-metallic phase at strong disorder.

Exponent-critical groups

Journal of Group Theory
Abstract We define and investigate the property of being “exponent-critical” for a finite group. A finite group is said to be exponent-critical if its exponent is not the least common multiple of the exponents of its proper non-abelian subgroups. We explore properties of exponent-critical groups and give a characterization of such groups.
